In 1999, seeking to reduce Philadelphia's homicide rate and put youthful offenders on the path to a productive adulthood, various Philadelphia agencies and organizations, including Public/Private Ventures, partnered to form the Youth Violence Reduction Partnership (YVRP). The project's goal is to steer youth, ages 14 to 24 and at greatest risk of killing or being killed, toward productive lives through increased support and supervision. This report describes YVRP and presents early evidence the initiative may be reducing homicides. Three appendixes are included: (1) Partners in the Development of YVRP; (2) The YVRP Team; and (3) Regression Equations. (Contains 15 endnotes, 4 figures, and 9 tables.)
